9.3 Data Collection

Physical Data collection

It is critical that the starting position is consistent on every line. Position the middle of the unit
with the starting line, and then push the system straight towards the end of the line. It is often
helpful to have a marker at the end so you have something to aim for.
Not all lines have to be finished. If there is an obstruction preventing you from finishing the line,
you can simply press Stop and end the line early.
In addition, not all lines have to be collected. If your area of interest is only 4m x 4m, set the
Grid Size to 5m x 5m, but don't collect the outer lines.

Data collection on the Display Unit

The data collection screen is shown in Figure 9-3. The right half of the screen is a graphic
representation of the grid, illustrating the size of the grid and the lines that need to be collected.
The left half of the screen will display the last grid line collected.
